CVE-2021-31897 describes a critical vulnerability in JetBrains WebStorm versions prior to 2021.1, allowing for remote code execution without user confirmation when opening untrusted projects. With a CVSS score of 9.8 (Critical), this vulnerability presents a significant risk due to its network-based attack vector, low attack complexity, and complete compromise of confidentiality, integrity, and availability.
